Easy Cheesy Chili Relleno Casserole

I remember being a newlywed, absolutely terrified of messing up dinner for my husband. One night, after a particularly stressful day, I stumbled upon a simplified chili relleno casserole recipe. The aroma of roasted chilis and melted cheese filled our tiny apartment, chasing away the day’s worries. That casserole, born from a desire to create something comforting, became a weeknight staple, a tangible expression of love and a reminder that even simple dishes can create lasting memories.

Recipe Overview

• Prep Time: 25 minutes
• Cook Time: 50 minutes
• Total Time: 1 hour 15 minutes
• Servings: 6
• Dietary Type: Gluten-Free (if using gluten-free flour)

Ingredients

• 4 (4 ounce) cans whole green chili peppers, seeded and drained
• Salt, to taste
• 1 cup evaporated milk
• 4 egg whites
• Tabasco sauce, to taste
• 1/3 cup all-purpose flour (or gluten-free all-purpose flour blend)
• 1/4 cup green onion, chopped
• 2 cups Monterey Jack cheese, shredded
• 2 cups sharp cheddar cheese, shredded
• 1 lb ground pork sausage, cooked and drained
• 1 (8 ounce) can tomato sauce
• 1 (8 ounce) can diced tomatoes, drained
• Sour cream, for serving

Equipment Needed

• 1 1/2 quart casserole dish
• Medium mixing bowl
• Second mixing bowl
• Disposable gloves (optional, but recommended)
• Measuring cups and spoons

Instructions

1. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius).
2. Lightly spray a 1 1/2 quart casserole dish with non-stick cooking spray. Set aside. This will prevent the casserole from sticking and make serving easier.
3. Wearing disposable gloves (highly recommended to avoid chili burn!), carefully slit the chili peppers in half lengthwise. Remove and discard the seeds from each pepper half. Rinse the peppers thoroughly under cold water and drain them on several layers of paper towels. Pat them dry to remove excess moisture.
4. Lightly salt the prepared chili peppers to enhance their natural flavor.
5. In a medium mixing bowl, whisk together the evaporated milk, egg whites, Tabasco sauce, and flour until the mixture is smooth and free of lumps. A few drops of Tabasco will add a subtle kick, but adjust to your preference. Set aside.
6. In a second mixing bowl, combine 1 cup of the Monterey Jack cheese, 1 cup of the sharp cheddar cheese, and the chopped green onions. Gently toss to combine. This cheese mixture will be layered within the casserole for maximum cheesy goodness.
7. Assemble the casserole: Layer half of the chili peppers evenly in the prepared dish. Next, spread half of the cheese mixture over the chili peppers. Then, distribute half of the cooked and drained ground pork sausage over the cheese.
8. Repeat the layering process: Add the remaining half of the chili peppers, followed by the remaining cheese mixture, and then the remaining ground pork sausage.
9. Pour the egg mixture evenly over the entire casserole, ensuring that all the layers are coated. This mixture will bind everything together and create a creamy, custardy texture.
10. Pour the tomato sauce and drained diced tomatoes evenly over the top of the casserole. This will add moisture and a tangy tomato flavor.
11. Bake in the preheated oven for 30 minutes.
12. Remove the casserole from the oven and sprinkle the reserved Monterey Jack and sharp cheddar cheeses evenly over the top.
13. Return the casserole to the oven and bake for an additional 20 minutes, or until the cheese is melted, bubbly, and lightly golden brown. A toothpick inserted into the center should come out clean.
14. Remove the casserole from the oven and let it sit for 5 minutes before serving. This allows the casserole to set slightly and makes it easier to slice.
15. Serve hot with a dollop of sour cream and a freshly tossed green salad dressed in olive oil and red wine vinegar. The cool sour cream and crisp salad will provide a delicious contrast to the warm, cheesy casserole.

Expert Tips & Tricks

• Don’t skip the draining step! Thoroughly draining the chili peppers and diced tomatoes is crucial to prevent a soggy casserole.
• Use a high-quality sausage. The flavor of the sausage will significantly impact the overall taste of the casserole, so choose a brand you enjoy. You can even experiment with different varieties, such as spicy Italian sausage or chorizo, for a unique twist.
• Customize the cheese. Feel free to substitute other types of cheese, such as Pepper Jack for a spicier kick or Colby Jack for a milder flavor.
• Make it ahead of time. The casserole can be assembled ahead of time and stored in the refrigerator for up to 24 hours before baking. Add an extra 10-15 minutes to the baking time if baking from cold.
• Broil for extra browning: If you want a more browned and bubbly cheese topping, broil the casserole for the last 1-2 minutes of baking, keeping a close eye to prevent burning.

Serving & Storage Suggestions

Serve the chili relleno casserole hot, straight from the oven. A dollop of sour cream, a sprinkle of fresh cilantro, or a side of guacamole can elevate the presentation and add complementary flavors.

Leftovers should be stored in an airtight container in the refrigerator. They will last for up to 3-4 days. To reheat, microwave individual portions or bake the entire casserole in a preheated oven at 350°F (175°C) until heated through. The casserole can also be frozen for up to 2 months. Thaw completely in the refrigerator before reheating.

FAQs (Frequently Asked Questions)

A: Place a baking sheet on the rack below the casserole dish to deflect some of the heat and prevent burning.

Q: Can I freeze this casserole after it’s been baked?
A: Yes, you can freeze the baked casserole. Let it cool completely, then wrap it tightly in plastic wrap and aluminum foil. Thaw overnight in the refrigerator before reheating.
